Abstract
This paper studies the coupled Korteweg-de Vries (KdV) equations that describe shallow two-layered water waves in ocean shores. The ansatz method is employed to retrieve the solitary wave solutions, topological and singular solitons of this coupled system of equations. The constraint conditions will fall out for the existence of these types of solitons. The study is also generalized to coupled KdV equations with power law nonlinearity. The numerical simulations supplement the analytical schemes.
